{"product_id":"aune-a17","title":"Aune A17 - Headphone amplifier","description":"\u003cp\u003eAune A17 is a flagship-class, fully discrete Class A headphone amplifier that also functions as a preamplifier. With a split power supply, precision volume control, and substantial power reserves, it drives everything from sensitive in-ear headphones to the most demanding over-ear models, with stable operation even during long listening sessions.\u003c\/p\u003e\n\u003cp\u003eThe input stage is built around twin JFET transistors that provide a natural, warm character reminiscent of tube amplifiers. Two current modes and four gain stages, combined with a 99-step R2R volume control (JRC MUSES72323), allow the drive to be precisely fine-tuned to your headphones. The output stage has three pairs of power transistors in parallel per channel, lowering the output impedance and improving both transient response and bass control.\u003c\/p\u003e\n\u003cp\u003eThe power supply is divided into high- and low-voltage sections: the preamp is powered by ±20 V for generous dynamic headroom, while the power amp runs at ±15 V for better thermal balance. The analog section is powered by a 100 W toroidal transformer with an 80,000 µF capacitor bank, while the digital control has a completely separate power supply with digital isolators to prevent interference. Everything is housed in a robust aluminum chassis with multilayer heatsinks for even heat distribution.\u003c\/p\u003e\n\u003cp\u003eThe connection panel features 4-pin XLR, 6.35 mm, and 4.4 mm headphone outputs, as well as both RCA and XLR inputs and outputs, making the A17 equally suitable as a dedicated headphone amplifier or as a preamplifier in a speaker system. All functions are controlled with dedicated buttons and mirrored on the included aluminum remote control.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: Fully discrete Class A headphone amplifier and preamplifier\u003c\/li\u003e\n\u003cli\u003eInput stage: Twin JFET\u003c\/li\u003e\n\u003cli\u003eVolume control: 99-step R2R (JRC MUSES72323)\u003c\/li\u003e\n\u003cli\u003eCurrent modes: 2\u003c\/li\u003e\n\u003cli\u003eOutput stage: 3 pairs of power transistors in parallel per channel\u003c\/li\u003e\n\u003cli\u003ePower supply: Separate ±20 V (preamp) \/ ±15 V (power amp) · 100 W toroidal transformer · 80,000 µF capacitor bank\u003c\/li\u003e\n\u003cli\u003eGain levels: 4 (G-1 = 5.8 dB, G-2 = 9.2 dB, G-3 = 11.6 dB, G-4 = 13.5 dB)\u003c\/li\u003e\n\u003cli\u003eOutput power: max. approx. 11.5 W @ 32 Ω (balanced), 2820 mW @ 32 Ω (6.35 mm)\u003c\/li\u003e\n\u003cli\u003eTHD+N: \u0026lt;0.0005 % @ 1 kHz\u003c\/li\u003e\n\u003cli\u003eSNR: \u0026lt;-115 dB @ 32 Ω\u003c\/li\u003e\n\u003cli\u003eChannel separation: \u0026lt;-100 dB @ 1 kHz, 32 Ω\u003c\/li\u003e\n\u003cli\u003eFrequency response: 20 Hz-80 kHz, ±0.05 dB\u003c\/li\u003e\n\u003cli\u003eNoise floor: ≤7 µV\u003c\/li\u003e\n\u003cli\u003eHeadphone outputs: 4-pin XLR, 6.35 mm (1 Ω), 4.4 mm (1 Ω)\u003c\/li\u003e\n\u003cli\u003eConnections: RCA and XLR inputs\/outputs (input impedance 10 kΩ; preamp output 200 Ω RCA \/ 100 Ω XLR)\u003c\/li\u003e\n\u003cli\u003eDimensions: 345 × 290 × 130 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 17 kg\u003c\/li\u003e\n\u003cli\u003eAccessories: power cable, 6.35 mm to 3.5 mm adapter, aluminum remote control, quick-start guide\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eOutput power per gain level:\u003c\/p\u003e\n\u003cdiv dir=\"ltr\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\"\u003eLast\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eG-1 (6.35 mm \/ balanced)\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eG-2 (6.35 mm \/ balanced)\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eG-3 (6.35 mm \/ balanced)\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eG-4 (6.35 mm \/ balanced)\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e32 Ω\u003c\/td\u003e\n\u003ctd\u003e480 \/ 1800 mW\u003c\/td\u003e\n\u003ctd\u003e1050 \/ 3920 mW\u003c\/td\u003e\n\u003ctd\u003e1800 \/ 6840 mW\u003c\/td\u003e\n\u003ctd\u003e2820 \/ 11500 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e100 Ω\u003c\/td\u003e\n\u003ctd\u003e160 \/ 640 mW\u003c\/td\u003e\n\u003ctd\u003e350 \/ 1370 mW\u003c\/td\u003e\n\u003ctd\u003e610 \/ 3400 mW\u003c\/td\u003e\n\u003ctd\u003e940 \/ 3720 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e150 Ω\u003c\/td\u003e\n\u003ctd\u003e105 \/ 420 mW\u003c\/td\u003e\n\u003ctd\u003e240 \/ 930 mW\u003c\/td\u003e\n\u003ctd\u003e410 \/ 1600 mW\u003c\/td\u003e\n\u003ctd\u003e630 \/ 2480 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e250 Ω\u003c\/td\u003e\n\u003ctd\u003e64 \/ 256 mW\u003c\/td\u003e\n\u003ctd\u003e140 \/ 560 mW\u003c\/td\u003e\n\u003ctd\u003e250 \/ 980 mW\u003c\/td\u003e\n\u003ctd\u003e380 \/ 1520 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e300 Ω\u003c\/td\u003e\n\u003ctd\u003e53 \/ 210 mW\u003c\/td\u003e\n\u003ctd\u003e120 \/ 470 mW\u003c\/td\u003e\n\u003ctd\u003e210 \/ 820 mW\u003c\/td\u003e\n\u003ctd\u003e320 \/ 1260 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e470 Ω\u003c\/td\u003e\n\u003ctd\u003e34 \/ 136 mW\u003c\/td\u003e\n\u003ctd\u003e76 \/ 300 mW\u003c\/td\u003e\n\u003ctd\u003e132 \/ 530 mW\u003c\/td\u003e\n\u003ctd\u003e200 \/ 810 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e600 Ω\u003c\/td\u003e\n\u003ctd\u003e26 \/ 104 mW\u003c\/td\u003e\n\u003ctd\u003e60 \/ 240 mW\u003c\/td\u003e\n\u003ctd\u003e100 \/ 410 mW\u003c\/td\u003e\n\u003ctd\u003e160 \/ 640 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"Aune","offers":[{"title":"Default Title","offer_id":53691982053714,"sku":"536919820537","price":26990.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/9454\/6667\/files\/Aune_A17__01_9d3fe898-3dfe-4065-8688-7011d213dc1c.jpg?v=1781013383","url":"https:\/\/maxxteknik.com\/en\/products\/aune-a17","provider":"Maxxteknik","version":"1.0","type":"link"}
